- the Gold Peak LiFePO4 batteries (see 0.3.09 release notes), or<br>

<br>
All caused by using a prototype EC firmware version that wasn't in<br>
manufacturing.<br>
<br>
The boot hang was designed by me. It will go away once you upgrade<br>
the firmware. See <a href="http://wiki.laptop.org/go/12297" rel="noreferrer" target="_blank">http://wiki.laptop.org/go/12297</a> for details.<br>
<br>
Please check the EC firmware version in all of your prototypes and<br>
upgrade it.<br>
<br>
On the machine you are having problems with, please do the following<br>
in a normal humid environment (e.g. > 50% RH), not a dry as a bone<br>
environment (e.g. < 25% RH); remove the power cable, the battery, wait<br>
30 seconds, then insert the power cable, the battery, and try again.<br>
<br>
When that doesn't work, carefully follow these steps;<br>
<br>
1. add battery, power cable, and bring the system to the ok prompt,<br>
<br>
2. check the battery LED is on and green,<br>
<br>
3. check the battery latch is locked,<br>
<br>
4. type "flash-ec! rom:ecimage.bin" and press enter,<br>
<br>
5. observe the consequences.<br></blockquote><div><br></div><div>Perfect, it rebooted many times and now contains EC Firmware 0.5.01, Q7C05 and 13.2.6 so all fixed, Thanks James!<br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
First, the machine should reprogram the SPI FLASH chip used by the<br>
EC. Next, it should reboot and the automatic Open Firmware upgrade<br>
will occur. Finally, it should reboot into 13.2.6.<br>
<br>
Let me know how it goes.<br>
